Layered titanoniobate complex pillared with [Al13O4(OH)24(H2O)12]7+ Keggin ions was prepared through a stepwise exchange process. By calcining this complex in air, the 1st alumina-pillared layered titanoniobate was obtained. The resultant pillared complex has a thermal stability over 500?and retains an interlayer distance of 1.34 nm after heating at 500?in air.

Key words: ALUMINIUM OXIDE, ION EXCHANGING, TITANATE, NIOBATE, OCTAHEDRAL
